screen goes blank on dell latitude d810 w/ 7.0 and DRMKMS

[John R. <mpweadh%hotmail.com@localhost>]

This is similar to kern/49768.  Shall I file another PR?  I can help
debugging this.

Seems there should be a way to disable the DRM like ACPI and SMP can be
disabled at the first boot prompt if there are issues.

I did the install on another machine, then moved the disk back to the
problem machine to get the dmesg below.  It works headless just fine.
